Significant tree damage implies severe winds and
should be reported to the NWS. You should report any time trees are
snapped or uprooted, and when limbs 2" or larger are broken off. When you
give your report, try to estimate the diameter of trees that have been uprooted
or snapped, or the size of limbs that are broken. Also, state the extent
to which the damage has occurred (one tree or limb versus numerous trees down).
Give the approximate time the damage occurred, if possible.
